I occasionally get accessories for the 3 and Y.  I currently have a storage box for the underside of the center console arm rest, a tray for the storage area under the arm rest, a tray for the front center console storage area, an under seat storage tray, and a white and black steering wheel cover.  These are after market items, not Tesla products.  $5 each.
